LT3504 - Quad 40V/1A Step-Down Switching Regulator

Datasheet Summary

Description

The LT®3504 consists of four 1A output current buck regulators.

The LT3504 has a wide operating input range of 3.2V to 40V.

An on-chip boost regulator allows each channel to operate up to 100% duty cycle and eliminates the need for four external charge pump circuits.
